Referring now more particularly to the accompanying drawings, the numeral l indicates in general a loom frame having the usual beam 2 and cloth roll 3. The lay is indicated in general by the numeral 4. Carried by the loom are the heddle frames 5 and 6 which are identical in construction and a description of one, therefore, will sumce for both.

The heddleframe forming a part of my automatic warp stop motion comprises a top rail l and a bottom rail 8 which are connected at their opposite ends by metal tubular end bars 9. The top rail l is provided at its opposite ends with end pieces 7 which are shaped to fit tightly about the ends of the rail. As best seen in Figure 5 of the drawings, the ends of the rails are slightly reduced on their sides and tapered to provide a snug fit in the metallic end pieces. Screwed through the upper end pieces are bolts A which look the tubular end bars and the end pieces 7' as a rigid unit.. The bottom rail 8 is of similar construction and is provided with and pieces 9 and bolts 13. It is pointed out that, as the rails TI and t may be removed, repairs or replacements to the heddle frame may be readily made. The rails l and 8 are preferably rectangular in cross section 2 and are preferably formed of wood. Formed in tending portions l8 of the bar.

the upper surface of the rail t is a series of grooves it which are rectangular in outline and which are disposed medially of the thickness of the rail. As best seen in Figure 4 of the drawings, these grooves are of a depth substantially one-fifth the height of the rail. The several grooves are separated by meansof a raised portion it disposed between adjacent ends of the grooves. Formed in each of the grooves, near its opposite ends, are recesses 92 and mounted in said recesses are springs 53 which are inclined upwardly to extend above the floor of'the grooves. The springs it are preferably held in position by means of screws id and, as. will be observed-the upper extremities;v

of the springs are curved downwardly to provide a smooth upper surface. Mounted in the grooves is a floatingfeeler bar which is indicated in general by the numeral it). As best seen in Figure 6 of the drawings, the floating feeler bar is preferably Y-shaped in vertical section and comprises a ii-shaped binding member is and contact members ll having theirupper extremities provided with laterally extending portions it. As will be observed, the greater portion of the contact members of the floating feeler bar are confined in adjacent relation within the binding member i6 and the lower end portion of the binding member it is rounded and adapted to engage the rounded upper end portion of the springs it. Secured to the bottom rail 8 at either side thereof are oppositely disposed guide straps 49 having laterally disposed inwardly presented flanges 26 at their upper ends. Two pairs of guide straps are pref erably employed for each feeler bar, a pair being disposed at each end of said bar with the flanges 20 normally in engagement with the laterally ex- The floating feeler bars will thereby be effectually retained in position in the grooves Ill. The straps iii are preferably secured in place by means of screws Mounted on the lower surface of the bottom rail 8, near one end, is a contact plate 22 which is preferably secured in'position by means of screws 23. The contact plate is provided with arounded lower surface 24. Connecting the plate rail 8 is a conductor 25., Mounted on the bottom rail 8, near the opposite end thereof, is a contact plate 26 which is electrically connected to the metal end bar 9 by means of an offset strap 21 and end piece 9.

Carried above the bottom rail 8 of the heddle frame in spaced relation thereto is a metal heddle bar 28 which is normally maintained in parallel spaced relationabove the floating feeler bars by means of heddle bar latches which will be described in detail hereinafter. The heddle bar is adapted to support the lower ends of heddles, a few of which are indicated by the numeral 29. A heddle bar 30 is supported in parallel spaced relation below the top rail i by means of the heddle bar latches.

The heddles, heddle bars, heddle end bar latches, and floating feeler bars cooperate for closing an electrical circuit in a manner to be described in more detail hereinafter.

Carried by the frame of the loom is a supporting frame it which is provided with a base 32 and diverging arms 33 terminating at their upper ends in bearings 34. Journaled through the bearings 34 is a tubular shaft 35-having' its end portions extending past the bearing 34 at either end. Associated with the shaft 35, near each end thereof, are upstanding levers 36 which form a part of what I have indicated as a grasshopper motion and as two of these motions are employed, the description of the construction of one of them will suflice for both. In addition to the upstanding lever 36, the grasshopper motion includes laterally extending parallel arms 31 and 38 which are best seen in Figure 2 of the drawings, the arm bl being pivoted to the lever 38 at its upper end portion and the arm 38 being pivoted to said lever 35 near the bearing, indicated by the numeral 39, which journals the shaft 35. Pivotally connected with the outer end portions of the arms 31 and 38 is a striking bar 40 which is provided at its upper end with an integral obliquely disposed supporting arm Al. Straddling the supporting arm 59 is a relatively long inverted U-shaped striking plate 42 having a striking surface 43 at its upper end. The lower end portion of the supporting plate 42 is adapted to receive an electrical conductor, a portion of which is indicated by the numeral 44.

In operation, these grasshopper motions are so disposed that the contact plates 22 and 26 on the bottomrails of the heddle frames 5 and 8 may make contact with the striking surfaces 43 of the striking plates. 42. The grasshopper motion, howevenis movable for shifting the striking surface into proper operative position relative to the heddle frames as said frames are moved to their lowermost position. The striking plate connected with the grasshopper motion disposed beneath the plate 22 is provided with a conductor 45 which extends into and throughout the length of the shaft 35 into a conduit 46 which is curved and disposed downwardly and extends to the shipperend of the loom. The conductor 44, which is connected to the striking plate of the grasshopper motion disposed beneath the plate 28, extends into the conduit 40. Surround ing the shaft 35 between the bearings 34 and Il are coiled springs 41. One end of one of the springs is locked to the supporting frame 3| whereas the other end-is tensioned against the lever 38 of one of the grasshopper motions. The spring carried on the opposite end of the shaft 35 is connected in a' like manner and said springs aeoaeee function to maintain the grasshopper motions under a continual tension.

Mounted on one end oi the loom frame is the shipper handle is which is pivoted to a bracket dd by means of a bolt so. The shipper handle is, of course, connected to suitable mechanism for controlling the loom so that when the shipper handle is shifted the loom is either started or stopped. As best seen in Figure 9 of the drawings, there is mounted'on an upright member bl of the loom frame l, near the shipper handle, a breaker contact 5! which is insulated from the upright by means of an insulating plate 52. Mounted on the shipper handle, near its lower end and disposed to confront the breaker contact bl, is a second breaker contact be which is insulated from the handle by means of an insulating plate t l. Mounted on the upright, near the upper end oi the loom, is a stub shaft 5t and swingingly mounted on said stub shaft is a shipper handle engaging member which is indicated in general by the numeral 5%. The shipper handle engaging member includes a curved arm bl! which extends across the edge of the shipper handle and has a wedging or cam action thereon, and a depending tongue it which is cut away to provide a stop iace 5d. Mounted on the upright oi the loom is a bracket 6d, the outer end of which is reduced to receive the face 59 of the tongue W. The bracket is secured in place by means of a bolt tit. Pivotally mounted on the bracket bd, near the outer end thereof, is an inverted yoke bl which is substantially U-shaped in cross section. As best seenin Figure? of the drawings, one of the legs of the yoke is slightly cut away to define a shoulder bl. A shoe M is Pivotally carried between the walls of the yoke. Connected with the yoke ti and disposed at right angles thereto is a lever 62'. Mounted on the upright bl" of the loom, substantially medially of its height, is an electro-magnet b3 and, as best seen in Figure 2 of the drawings, the electromagnet is provided with a pivoted armature t l. Connecting the outer end portion of the pivoted armature M with the lever 62' is a metal rod tit. The rod is severed and a turnbuckle 6t connects the severed end portions so that adjustment between the armature and the lever may readily be eflected. 7

By referring to Figure l of the drawings, it will be seen that the conductor M is connected to one to M a conductor dd is connected to one side of a suitable power circuit. It is to be'understood that the power circuit may comprise a regular lid volt supply circuit or a step-down transformer or batteries may be employed in lieu of the 110 volt power circuit, if desired. The conductor M is carried to the power source through a conduit till. The. other side of the power circuit is acted to the breaker contact 53 by means or a conductor tit which extends through the conduit Connecting the breaker contact bi with the other terminal of the electro-met is a conductor dd.

Swingingly connected withthe tongue Fit, in-

ediate of its length and extending above the bracket dd, is a pawl bar it having a pawl M at its outer end. As seen in Figure l, the inner end of the pawl bar is swingingly mounted in a chat formed in the tongue at. Pivotaliy mounted on the side face of the pawl bar, near its pivoted end, is a dog "It and .mounted beneath the dog is a pin it. A'spring it is to the h of the shipper s; en-

oi the electro-inagnet whereas the gaging member to resiliently contact the upper surface of the pawl bar and normally maintain said bar under downward tension. The pin l2 limits downward swinging movement of the lock ing dog it. Mounted on the lay i, at its upper end, and beneath the race plate thereof, is a bracket it and screwed through the lower end of said bracket it is a bolt it having a head it winch is provided with a substantially V-shaped notch it. The bolt is, of course, adjustable in the bracket and is held in adjusted position by means of. a lock nut it.

In operation, the heddle frames are shifted up and down for forming the shed to permit the feeler bar disposed therebeneath. When the frame carrying the broken warp thread is shitted downwardly, contact will be made through the heddle, str' z plate of the grasshopper motion disposed therebeneatl'i,- and thence through the conductor M to one side of the electro-magnet. The circuit is completed through the floating feelerbar, conductor '25, and contact plate 2%, to the plate of the other grasshopper motion and thence to the conductor and to one side of the power circuit. The other side of the power circuit is connected to one oi'the breaker contacts and the mating breaker contact is connected to the electro-magnet. A; complete electric circuit will thereby be formed. The armature ti t of the electro-magnet will be rocked i'or shifting the yoke and shoe into engagement with the pawl bar it and shifting said bar upwardly so that the pawl ill will be disposed in the path of the bolt lth'which is provided with the head it, as the layv is swung. The heddle frames make but momentary contact with the grasshopper motions, so that further shifting ofsaid frames will break the circuit. The pawl bar must then be held up into-the line of travel of the bolt on the lay until the lay swings the bolt into contact therewith. After the momentary contact with the grasshopper motions by the heddle frame and the upward shifting of the pawl bar, therefore; the pawl bar will be held. upwardly by enement oi" the locking dog it behind the shoulder bl until thelay ssthe bolt it into engagement with said bar. The pin it will limit the downward swinging movement of the dog 172 so thatthe dog will always be maintairied in proper position. When the head it engages the pawl ii, the pawl bar, by the force oi the ting lay, is g so that the shipper handle engaging member rocks on the edge or the shipper handle and swings the shipper handle to inoperative position so that the loom will immediately come to a stop. The breaker contacts ti and bi! are, of course, separated by the shift-' heddle bar and contact plate 2% to thedle to operative position for starting the loom.

The breaker contacts 5| and 53 will be again connected so that the device will be in readiness for another break in the warp thread or threads,

should one occur.

Connecting the heddle bars 28 and 38 with the top and bottom rails of the heddle frame, are heddle bar latches which are indicated in general by the numeral '78. The heddle bar latch 18 is shown in detail in Figures 10 and 11 of the drawings and reference is particularly directed thereto. The heddle bar latch comprises a threaded shank 19 which is tapered toward its lower end and is preferably sunk into the upper surface of the rails of the heddle frame. The shank is reduced in thickness at the upper end of the threaded portion and is projected upward- 1y, flattened and enlarged in width to define a keeper plate 89 which extends above the shank a distance substantially equal to the length of the shank itself. The mid-portion of the keeper plate is cut away throughout substantially half its width to define a bar-receiving recess 8i which is rectangular in shape and is adapted snugly to receive the heddle bar therein. Extending transversely through the keeper plate 80, below the bar-receiving recess in spaced relation there,- to and medially of the width of the keeper plate, is a stop pin 82. As will be observed, the pin 82 projects at either side of the plate. Extending through the upper end portion of the keeper plate 88 is a guide pin 88. Formed on the keeper plate within the recess is a lug 83 which is adapted to project through an aperture in the end of the heddle bar. The lug is of a length equal to the thickness of the heddle bar.

Normally straddling the keeper plate tit, throughout the major portion of its length, is a substantially inverted U-shaped preferably spring steel keeper a l which is provided with a bight portion 85 at its upper end andparallelwalls 86. The opposite corresponding edges of the walls 86 are formed with serrations at which will ren= der the keeper adaptable for ready manual engagement. Formed-in the walls 86 near the upper end of the keeper and medially of the width of said walls are alined longitudinally extending oblong slots 88which receive the guide pin 88 therethrough and the keeper is thereby permitted to slide vertically upon the keeper plate for a distance substantially equal to the length of the slot. Formed on the walls 86 are depending alined lugs-89 which are slightly bowed toward each other and which are provided with rounded alined bar-engaging edges 88. The lugs normally extend into the bar-receiving recess throughout substantially three-fourths of the length of said recess and are adapted to engage one of the walls of the heddle bar lying in said recess for firmly clamping the bar in position in said recess. In

- view of the fact that the keeper is preferably formed of spring .steel, the lugs 88 will snap into place when the keeper is shifted downwardly to locked position on the keeper plate. The keeper plate is projected downwardly to a point below the stop pin '82 to define parallel guide fingers SE. The corresponding lower end portions of the guide fingers 9! are turned upwardly upon themselves to define lower guide slots 92, which slidably receive the pin 82, so that when the keeper is shifted downwardly intolocked position, the

keeper plate will be maintained in proper slidable relation to the plate. The guide pin 82 will provide a guide so that the keeper will be guided into proper position with the lugs 89 in clamping relation to the heddle bar lying in the barreceiving recess8l. The fingers 9| will cooperate with the lugs 89 for firmly clamping the beddle bar in locked position. It will be understood that the keeper and lug 90 will cooperate to retain a heddle bar in the heddle bar latch, and will effectually limit said bar against lateral and longitudinal movement in the heddle frame. When it is desired to release the heddle bar and remove it from the bar-receiving recess, it is only necessary to grasp the keeper at the serrated portion 81 and slide the keeper upwardly. This will disengage the lugs 88 from the heddle bar and will permit the ready removal of the heddle bar from the recess M. It will be observed that, as the keeper is shifted upwardly, the bowed lug II will engage the keeper plate 88 at the upper edge defining the recess so that the walls 88 of the keeper, and consequently the guide fingers 8|, will be slightly spread apart which will permit more ready shifting of the keeper on the guide pins so that complete access may be gained to the recess. By removing the pins 82 and 88; it is, of course, possible to remove the keeper 84 if need for repair or replacement should develop.

The numeral 93 indicates a heddle bar latch which is of identical construction to the latch it but wherein the lug 90 is omitted. The latch 93 is adapted for use at points between the ends of the lower rail, and is used in the same manner as the latch 18.

It is particularly emphasized that in my improved warp stop motion, 1 have utilized the heddle frame for completing the circuit so that it is not necessary to employ separate drop wires and other attendant mechanism as is common on the old style warp stop motion. Attention is further directed to the fact that the heddle frame employed not only functions in its usual manner, that is of supporting the heddles and warp threads, but also serves as an electric switch for closing an electric circuit and stopping the loom as hereinbefore described. It is to be further emphasized that the floating feeler bar is mounted within the confines of the bottom rail of the frame so that a minimum amount of space is utilized without sacrificing the efilciency of the mechanism. The fact that the floating ieeler bars are resiliently supported will insure long life and also positive electrical connection between a dropping heddle and said bar. It should be still further emphasized that the well-known lay also serves a dual duty in my invention in that the bolt and head carried thereby are utilized for shifting the shipper bar to inoperative position and consequently breaking the electrical circuit.

By utilizing my grasshopper motion the contact plates carried thereby will be disposed in proper position for the respective heddle frames asthey are shifted downwardly in the usual manner so that the electric circuit may be completed effectually.

It is believed that from the foregoing description it will be seen that I have provided a warp stop motion which will operate very efliciently over a hing period of time with practically no attention.
